For the first time in the range of Manufacture Vacheron Constantin calibers, this self-winding movement with its 51-hour power reserve is equipped with a remarkable peripheral oscillating weight. Mounted on ball bearings, this unusual construction provides a perfectly clear view of Caliber 3500, entirely hand-decorated in keeping with the watchmaking traditions. This peripheral structure also serves to preserve the exceptional slimness of the world’s thinnest self-winding split-seconds chronograph movement.
To signal its membership of an exclusive series dedicated to the 260th anniversary of the manufacture, the peripheral oscillating weight of the Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin bears the dedicated scrolling pattern specifically created by the brand’s designers for this occasion. This unusual motif, also known as “fleurisanne engraving” is inspired by the arabesques adorning the balance-cock of the oldest pocket watch from the Maison, signed by Jean-Marc Vacheron in 1755.
